DEVICE FOR ADJUSTING THE BEAT OF CLOCK-PENDULUMS.

SPECIFICATION forming part of Letters Patent No. 551,234, dated December10, 1895.

Serial No. 542,014. (No model.)

To all whom it may concern:

Be it known that I, FRED F. RIOHEY, of Topeka, in the county of Shawneeand State of Kansas, have invented a new and Improved LevelingAttachment for Clocks, of which the following is a full, clear, andexact description.

My invention relates to a leveling attachment for clocks, and it has forits object to provide a device adapted for attachment to a clockmechanism, which attachment will control the pendulum and verge of theclock to such an extent that it will act properly even though the clockshould be considerably out of plumb; and a further object of theinvention is to make an attachment for the purpose above described whichwill be exceedingly simple, durable and economic.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a front elevation of aportion of a clock mechanism and theattachment applied thereto. Fig. 2 is a side elevation of the saidattachment applied to the clock; and Fig. is a sectional view of apivot-support for a balance-frame, constituting the main feature of theinvention.

In carrying out the invention the clock mechanism A may be of anydesired construction, and the verge-wheel shaft 10, which is shown inthe drawings, is journaled in the frame of the clock mechanism at theback and in a bracket 11 projected from the frame at the front; and thebearing, whether it be the bracket 11 or the back of the said frame, ispreferably constructed as shown in Fig. 3, in which it is formed with aboss 12, the said boss having a stud 13 attached thereto and integraltherewith, and extending horizontally outward. The upper ends of themembers of a U-frame B are pivoted on the said studs 13, and are held inposition on the studs by means of set-screws 14C or a similar device.

The U frame B has one of its vertical members at the front center, andthe other at practically the rear center of the clock mechanism, and thefront member of the U-frame is curved to a greater or less extent to theright from the center, as shown in Fig. 2, being at all times in frontof the verge-rod, while the rear memberis more or less straight. The U-frame at a point at the rear of the center of its bow member isprovided with apendent member B, upon which a weight B is suspended,which will balance the said U- frame and keep the rear member plumb nomatter how much out of plumb the clock mechanism may sit. A block or bar15 is pivoted upon the inner face of the front member of the weightedU-frame, and in the bottom portion of this block or bar 15 the spindle16 of the verge 17 is journaled at one of its ends, the opposite endbeing held in the usual spring 18. Thus it will be observed that theverge is carried by the weighted swinging frame B, and the pendulunrrod19 at its upper end, after having passed through the verge, is securedin the usual manner to a post 20, which is also secured to the back ofthe forward member of the said weighted frame. Thus it will be observedthat both the pendulum and the verge will be kept perfectly plumb byreason of the weighted frame B being constantly in that positionirrespective of the frame carrying the clock mechanism proper.

The device is exceedingly simple, durable and economic, and isapplicable to any form of clock mechanism. The usual verge-wheel 22 isprovided for engagement with the verge, and it will be further observedthat the swinging frame will control the verge and pendulum to such anextent that the frame of the clock mechanism A may be considerably outof plumb, provided the pendulum and verge in their swinging movement arenot brought in contact with any offsets on the frame.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In a leveling attachment for clocks, the combinationof a frame, a verge wheel and its shaft journaled therein, bearingsformed on said frame and projecting therefrom in axial alignment withand at opposite ends of frame, said pendulum extending below the IO saidU-shaped frame and to one side of the bent arm of the same,substantially as set forth.

FRED F. RIGHEY.
